Tegra30 I2S driver syncs regmap cache only on resume from system suspend,
but hardware is reset across the runtime suspend because RPM of the parent
AHUB driver resets the I2S hardware, hence h/w state is lost after each
RPM resume. The problem isn't visible because hardware happens to be fully
reprogrammed after each RPM resume. Move hardware syncing to RPM resume in
order to restore h/w state properly.

The I2S reset may be asserted at a boot time, in particular this is the
case on Tegra20 AC100 netbook. Tegra20 I2S driver doesn't manage the
reset control and currently it happens to work because reset is implicitly
deasserted by the tegra-clk driver when I2S clock is enabled. The I2S
permanently stays in a reset once tegra-clk is fixed to not touch the
resets, which it shouldn't be doing. Add reset control to the Tegra20
I2S driver.
Note that I2S reset was always specified in Tegra20 device-tree, hence
DTB ABI changes aren't required.

Audio Graph Card based Tegra driver is only useful on NVIDIA Tegra SoCs.
Hence add a dependency on SND_SOC_TEGRA, to prevent asking the user
about this driver when configuring a kernel without Tegra sound support.
Wrap all Tegra sound config options inside a big if/endif block, instead
of just adding the dependency to the single config option that does not
have it yet, to preventing similar future mistakes.

AHUB driver misses D_AUDIO and APBIF resets. CPU hangs on trying to
access hardware if resets aren't de-asserted. This problem is currently
masked by the tegra-clk driver which implicitly de-asserts the resets when
the corresponding clocks are enabled. Soon the implicit de-assertion will
be gone from the tegra-clk driver, thus we need to fix the AHUB driver.
Add the missing resets to the driver.

This series adds audio graph based sound card support for Tegra210
platforms like Jetson-TX1 an Jetson-Nano. The following preparatory
audio graph enhancement series is already merged.
* https://patchwork.kernel.org/project/alsa-devel/list/?series=375629&state=*
Following are the summary of changes:
* Add graph/audio-graph based schemas or schema updates for Tegra210
component and machine drivers.
* Add Tegra audio graph machine driver.
* Add required DT support for Jetson-TX1/Nano.
This work is based on earlier discussion of DPCM usage for Tegra
and simple card driver updates.

is now merged. Resending this now to appear in the top of the mail list.
Changelog
=========
v5 -> v6
--------
* Added ports or port description in YAML docs for Tegra AHUB
devices and graph card in patch 1/6 and 2/6. Reference of
audio-graph-port.yaml is used for AHUB devices.
* Dropped redundant NULL check return for of_device_get_match_data()
in patch 3/6.

2.7.4
Add Tegra audio machine driver which is based on generic audio graph card
driver. It re-uses most of the common stuff from audio graph driver and
uses the same DT binding. Required Tegra specific customizations are done
in the driver and additional DT bindings are required for clock handling.
Details on the customizations done:
- Update PLL rates at runtime: Tegra HW supports multiple sample rates
(multiples of 8x and 11.025x) and both of these groups require different
PLL rates. Hence there is a requirement to update this at runtime.
This is achieved by providing a custom 'snd_soc_ops' and in hw_param()
callback PLL rate is updated as per the sample rate.
- Internal structure 'tegra_audio_graph_data' is used to maintain clock
handles of PLL.
- The 'force_dpcm' flag is set to use DPCM for all DAI links.
- The 'component_chaining' flag is set to use DPCM with component model.

2.7.4
ADMAIF is the interface between ADMA and AHUB. Each ADMA channel that
sends/receives data to/from AHUB must intreface through an ADMAIF channel.
ADMA channel sending data to AHUB pairs with an ADMAIF Tx channel and
similarly ADMA channel receiving data from AHUB pairs with an ADMAIF Rx
channel. Buffer size is configurable for each ADMAIF channel, but currently
SW uses default values.
This patch registers ADMAIF driver with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes ADMAIF interfaces, which can be used to connect different
components in the ASoC layer. Makefile and Kconfig support is added to
allow to build the driver. The ADMAIF device can be enabled in the DT via
"nvidia,tegra210-admaif" compatible binding.
Tegra PCM driver is updated to expose required PCM interfaces and
snd_pcm_ops callbacks.

The Digital Speaker Controller (DSPK) converts the multi-bit Pulse Code
Modulation (PCM) audio input to oversampled 1-bit Pulse Density Modulation
(PDM) output. From the signal flow perpsective, the DSPK can be viewed as
a PDM transmitter that up-samples the input to the desired sampling rate
by interpolation then converts the oversampled PCM input to the desired
1-bit output via Delta Sigma Modulation (DSM).
This patch registers DSPK component with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes DSPK interfaces, which can be used to connect different
components in the ASoC layer. Makefile and Kconfig support is added to
allow to build the driver. The DSPK devices can be enabled in the DT via
"nvidia,tegra186-dspk" compatible binding. This driver can be used
on Tegra194 chip as well.

The Audio Hub (AHUB) comprises a collection of hardware accelerators for
audio pre/post-processing and a programmable full crossbar (XBAR) for
routing audio data across these accelerators in time and in parallel.
AHUB supports multiple interfaces to I2S, DSPK, DMIC etc., XBAR is a
switch used to configure or modify audio routing between HW accelerators
present inside AHUB.
This patch registers AHUB component with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes AHUB interfaces, which can be used to connect different
components in the ASoC layer. Currently the driver takes care of XBAR
programming to allow audio data flow through various clients of the AHUB.
Makefile and Kconfig support is added to allow to build the driver. The
AHUB component can be enabled in the DT via below compatible bindings.
- "nvidia,tegra210-ahub" for Tegra210
- "nvidia,tegra186-ahub" for Tegra186 and Tegra194

Audio Client Interface (CIF) is a proprietary interface employed to route
audio samples through Audio Hub (AHUB) components by inter connecting the
various modules.
This patch exports an inline function tegra_set_cif() which can be used,
for now, to program CIF on Tegra210 and later Tegra generations. Later it
can be extended to include helpers for legacy chips as well.

Tegra PMC clock clk_out_1 is dedicated for audio mclk from Tegra30
through Tegra210 and currently Tegra clock driver keeps the audio mclk
enabled.
With the move of PMC clocks from clock driver into pmc driver, audio
mclk enable from clock driver is removed and this should be taken care
of by the audio driver.
tegra_asoc_utils_init() calls tegra_asoc_utils_set_rate() and audio mclk
rate configuration is not needed during init and the rate is actually
set during the ->hw_params() callback.
So, this patch removes tegra_asoc_utils_set_rate() call and just leaves
the audio mclk enabled.

Tegra PMC clock clk_out_1 is dedicated for audio mclk from Tegra30

With the move of PMC clocks from clock driver into PMC driver, audio

using assigned-clock-parents property and audio mclk control should be
taken care of by the audio driver.
This patch has implementation for parent configuration when default
